Comic
Strip
• Create a comic strip to describe a
viral reproduction cycle.
– If you are at a “1 OR 3”, you are
doing the lysogenic cycle.
– If you are at a “2 OR 4”, you are
doing the lytic cycle.
• Your comic should be 6 “slides”,
colored, and be the cycle in STORY
format
• You must include 6 words from
your vocab list (highlight,
underline, or circle them in your
comic)
• Minimum of 5 COLORS!
• DUE FRIDAY!!!

Essential Question
How is the structure of bacteria
related to their function?
Standard
11C – summarize the role of microorganisms in both
maintaining and disrupting the health of both
organisms and ecosystems.
A prokaryote is a
unicellular
organism lacking a
membrane-bound
nucleus or
organelles.
Robert Hooke and Anton
van Leeuwenhoek, with
the invention of the
microscope, “opened
our eyes to the hidden,
living world around us”.
Prokaryotes are divided
into two very different
groups: eubacteria and
archaebacteria.
Eubacteria is
the larger of
the two
kingdoms.
Eubacteria live
everywhere.
Eubacteria are
usually surrounded
by a cell wall. Its two
main functions are
to protect the
organism from injury
and to determine its
shape.
The cell walls of
eubacteria contain
peptidoglycan.
Archaebacteria lack the
peptidoglycan of eubacteria and also
have different membrane lipids.
Some scientists believe that
archaebacteria may be ancestors of
eukaryotes because the DNA
sequences of key archaebacterial
genes are more like those of
eukaryotes than those of eubacteria.
Archaebacteria can be found in some
extreme environments including
oxygen-free areas, thick mud, the
digestive tracts of animals, and
extremely salty or hot water.
Prokaryotes are identified based upon
their shape, the chemical nature of
their cell walls, the way they move, and
the way they obtain energy.
Bacterial shapes:
• Bacilli – rod-shaped
• Cocci – spherical
• Spirilla – corkscrew-shaped
Gram-positive
and Gramnegative are the
two different
types of cell
walls.
Gram staining is a
method used to
tell them apart.
Bacterial movement:
• Some are propelled by flagella
which are whip-like structures.
• Some lash, snake, or spiral
forward.
• Others glide slowly along a layer
of slime-like material they
secrete.
• Some don’t move at all.
Bacteria use
two processes
to release
energy: cellular
respiration,
fermentation,
or both.
Two factors
hold the
growth of
bacteria in
check: the
availability of
food and the
production of
wastes.
Binary fission is when a bacterium divides in half through mitosis. Both
resulting cells are genetically identical.
Conjugation is also called “bacteria sex”. DNA is passed from one bacterium
to another through a pilus
Bacterial Conjugation
Bacteria Collection Timer
-You will have 7 minutes to collect a sample.
-You can swab whatever you want….stay on the 1st floor (English Hallways,
Cafeteria, Cafeteria Hallway ONLY!!!).
-You will work with a partner.
-Use a Q-tip to “swab” your contaminated area and gently streak it onto your
petri dish. (Ask me to show you how)
-Throw away the Q-tip.
-Cover your petri dish.
-Flip your covered petri dish upside down and label the bottom with “Period #
and your group members’ initials”.
-Tape the edges, leave it upside down, and give it to me.
-If you are not back in this room in 7 minutes, you will be counted tardy to class.
